While most undergraduate construction curricula are designed to improve SL, no recent study was found to have assessed undergraduate construction students’ SL skills. Therefore, the purpose of this research was to assess the SL attitudes, skills, and self-efficacy of 46 undergraduate construction students. Data was obtained through students’ completion of the standard 28-item Test of Scientific Literacy Skills (TOSLS) instrument; a student self-reporting SL self-efficacy survey; and focus group discussions. Results revealed that despite the overall mean SL self-efficacy score of 3.42 on the 5-point Likert scale, the mean TOSLS test score was 43%. The mean female TOSLS test score was approximately 7% higher than the mean male score; and the mean test score of senior construction students was 19% higher than that of the freshmen. This was statistically significant (p<0.05) and provided an indication that the construction program had somewhat contributed to the improvement of students’ SL skills; however, additional curriculum improvements are necessary to improve SL skills of construction students. The students’ best test performance was related to identifying valid science arguments and evaluating the misuse of scientific data; while their weakest performance was related to their somewhat weak quantitative aptitude. Their TOSLS problem solving quantitative scores were significantly (p<0.001) lower than TOSLS valid scientific argument scores. These results correlated well with departmental data associated with students’ struggles with courses such as ‘Surveying’ that need advanced quantitative skills. Overwhelmingly, construction students had positive attitudes towards science and mathematics, and agreed that these skills are needed for career success. This study demonstrates the need for curriculum improvements that will strengthen the SL skills of construction students. Furthermore, contributions add value to knowledge base necessary to advance construction education research on scientific literacy skill development. Insights provided may be used to guide construction curriculum improvement, with increased emphasis on quantitative skills for solving real-world problems. Strategies such as tutoring, mathematics laboratories, and math placement tests could increase students’ SL skills and better prepare them for careers in the construction industry. In the long-term, a more SL Built Environment workforce will have improved abilities and be better prepared to make evidence-based decisions that will transform global built environments. Introduction Undergraduate education should provide students with knowledge and experiences that will shape their capability and confidence in scientific reasoning and making evidence-based decisions that will advance progress made by organizations engaged in engineering, construction, infrastructure, and the built environment [1- 4]. The United States is one of the nations that believes that it is important for its leaders and citizens to be scientifically literate. A scientifically literate citizen needs to have: (1) a basic vocabulary of scientific terms and constructs; and (2) a general understanding of the nature of scientific inquiry [5, 6]. The six elements of science literacy are: (a) understanding basic science concepts, (b) understanding nature of science, (c) understanding ethics guiding scientists’ work, (d) understanding interrelationships between science and society, (e) understanding interrelationship between science and humanities, and (f) understanding the relationships and differences between science and technology [7]. The proportion of U.S. adults qualifying as being scientifically literate is now 28% and has doubled over the last two decades, but the current level is still problematic for a democratic society that values citizen understanding of major national policies and participation in the resolution of important policy disputes [8]. Scientific literacy and reasoning ability was found to be a strong predictor of self-efficacy, which is a can-do attitude that allows students to persist and be successful, even under extremely challenging circumstances [9]. Developing formal and informal reasoning ability is a primary factor influencing self-efficacy [9]. The engineering and construction industry will benefit from undergraduate education which prepares students who have high levels of scientific literacy and self-efficacy, and consequently, are able to reason, argue, and make decisions after their evaluation of evidence. The creation of learning environments that develop students’ abilities to reason from evidence and participate in scientific argumentation is considered a priority in education reform [10, 11]. The National Science Foundation and the National Academy of Science recognize the importance of developing flexible frameworks that fosters transformative changes to curriculums, pedagogical approaches and academic culture. The National Research Council emphasizes that science should be nonnegotiable a part of basic education, because some knowledge of science is essential for everyone [12]. Specifically, school science education should promote scientific proficiency because: 1. Science is a significant part of human culture and represents one of the pinnacles of human thinking capacity; 2. It provides a laboratory of common experience for development of language, logic, and problem-solving skills in the classroom; 3. A democracy demands that its citizens make personal and community decisions about issues in which scientific information plays a fundamental role, and they hence need a knowledge of science as well as an understanding of scientific methodology; 4. For some students, it will become a lifelong vocation or avocation; and 5. The nation is dependent on the technical and scientific abilities of its citizens for its economic competitiveness and national needs [12]. Upon graduation from undergraduate construction programs, graduates are engaged in the design, planning, engineering, construction, estimating/budgeting, management, quality assurance/control, operations, maintenance, and demolition of the nation’s buildings and infrastructure. Their position titles include but are not limited to Field Engineer, Superintendent, Supervisor, Transportation Technician, Project Engineer, Project Inspector, Project Manager, Estimator, and Safety Director. In these roles, graduates need the knowledge and confidence to make decisions related to construction materials, labor, equipment, subcontractors, schedules, costs, sustainability, safety, and quality. There is the need for facts and evidence-based decision when leaders of the engineering and construction industry are providing solutions to emerging problems associated with smart buildings, smart infrastructure, interconnected systems, energy consumption, efficient technologies, global partnerships, and other similar sweeping transformations in the built environment [2]. Despite the critical role to be played by construction graduates upon entry into their professional careers, it appears from anecdotal evidence that their scientific literacy and evidence-based reasoning skills may not be as high as needed to excel in this globally competitive environment. While most undergraduate construction curricula are designed to improve SL, no recent study was found to have assessed undergraduate CM students’ SL skills. Consequently, the primary goal of this research was to assess the scientific literacy skills, attitudes, and self-efficacy of construction students at a historically black university. Specifically, the study had the following objectives: 1. Assess construction students’ attitudes to mathematics and science; 2. Assess the scientific literacy skills of construction students; 3. Assess the scientific literacy self-efficacy of construction students; Methodology This research utilized a mixed methods approach to assess the SL skills, attitudes, and self- efficacy of 46 undergraduate construction students. Data was obtained through students’ completion of the standard 28-item Test of Scientific Literacy Skills (TOSLS) instrument; a student self-reporting SL self-efficacy survey; a student self-reporting mathematics self-efficacy
